Experimental Evaluation of Sample-Number Dependence of Spatial Resolution in PPRM-OCDR

Periodic pseudo-random modulation (PPRM) has recently been introduced to improve the spatial resolution of optical correlation-domain reflectometry (OCDR). In this study, we experimentally examined how the number of samples in one PPRM period affects OCDR performance. The spatial resolution improved as the sample number increased and reached its minimum at approximately 2000 samples, indicating the presence of an optimal sampling condition. These results provide practical guidelines for selecting modulation parameters in PPRM-OCDR systems. © 2026 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.

期刊介绍： IEEJ Transactions on Electrical and Electronic Engineering (hereinafter called TEEE ) publishes 6 times per year as an official journal of the Institute of Electrical Engineers of Japan (hereinafter "IEEJ"). This peer-reviewed journal contains original research papers and review articles on the most important and latest technological advances in core areas of Electrical and Electronic Engineering and in related disciplines. The journal also publishes short communications reporting on the results of the latest research activities TEEE ) aims to provide a new forum for IEEJ members in Japan as well as fellow researchers in Electrical and Electronic Engineering from around the world to exchange ideas and research findings.
